Problems Publishing with both Articulate 2 & 3

I'm having a problem publishing my courses. I can preview just fine, however when I publish to Web or LMS and click 'View' when it is complete, the skin opens but the session never plays. Even sessions that worked in the past are giving me the same problem. Does anyone know of a solution?

I've attached one of the three I've been trying to publish in hopes someone can tell me what I've done wrong.

Hi Wendy. Thank you for responding, I'm hoping to resolve this before Monday.

I tried uploading it to Dropbox and asked a peer to try it, if that is what you are referencing. This is my personal computer and I don't have a LMS in which to test it. The weird thing is I had no problems prior to loading Storyline 3. This is my first attempt since my Storyline 3 download and now the Storyline 2 session will not play as well.
